Very Unadvanced Product

I bought this program to help my son, who is at the end of Saxon Calculus in high school (maybe equivalent to Calc II?). I find it increasingly difficult to help my kids at this point and thought I would make my life easier. This program not only does not do trigonometric substitution, as mentioned in a previous review, it also does not apply l'Hopital's rule when evaluating limits. In the one case the problem remains unsolved, in the second case an incorrect answer is given with no indication that it could be incorrect. I entered a third problem from my son's homework and it presented an incomplete answer, refusing to fully evaluate the limit of a natural logarithm. I have not continued to explore for further short-comings since these came up in the second half-hour of using the program.
The first half hour of using the program was a painful exercise in figuring out how to actually use it. It is an extremely clumsy program, having such things as an annoying graphic of a large pencil which obscures parts of the problem and takes a large chunk of screen with it when it moves around. It can only be turned off temporarily. When inserting a symbol, it is necessary to first select insert and then click again on the page. More annoying, it is impossible to place the cursor within a problem by clicking on the spot - the arrow keys must be used.
I suppose I would be able to put up with the with such clumsy annoyances if we actually found the program to be helpful. If your student needs help with very basic calculus, "Calculus Solved!" might be worth the money and effort. However, if you have a bright student struggling with more advanced problems, it is simply a waste of money. I am sorry I bought it.
